Dolphin stopped using password in KWallet

When I try to connect to a remote, I get asked for the credentials. Instead it should be using the ones I have already stored.

This used to work but it stopped in the last month or so and with other applications it still does.

I have this behavior on two different hosts, both running an up to date KDE Neon. I’m not aware, that I have changed anything in this regard on either host.

When I run Dolphin from the shell I get the following message immediately:

Qt: Session management error: None of the authentication protocols specified are supported

When I take a look at the Applications tab in KWalletManager, Dolphin is not shown.

Does anyone have any suggestion or idea on how to approach this issue?

The recent Plasma 6.1 update fixed the issue.
